They were ten miles from the city's central core. The last days of travel had been a game of hopscotch, seeking out the dry places and segments of passable roadway, hacking their way through thickets of spiny, insect-infested vegetation. In these quarters, nature unveiled its true malevolent purpose: everything here wanted to sting you, swarm you, bite you. The air creaked with its saturated weight and miasma of rot. The trees, gnarled like grasping hands, seemed like something from another age entirely. They seemed positively made up. Who would invent such trees?

Darkness came on with a chemically yellowish dimming. The trip had compacted to a crawl. Even Amy had begun to show her irritation. Her signs of illness had not abated; rather, the opposite. When she thought Greer wasn't looking, he caught her pressing her palms to her stomach, exhaling with slow pain. They quartered that night on the top floor of a house that seemed outrageous in its ruined opulence: dripping chandeliers, rooms the size of auditoriums, all of it spattered with a black, off-gassing mold. A brown line three feet above the marble floor circumscribed the walls where floodwaters had once risen. In the massive bedroom where they took shelter, Greer opened the windows to clear the air of the ammonic stench: below him, in the vine-clotted yard, lay a swimming pool full of goo.

All night long, Greer could hear the dopeys moving in the trees outside. They vaulted from limb to limb, like great apes. He listened to them rustling through the foliage, followed by the sharp animal cries of rats and squirrels and other small creatures meeting their demise. Amy's injunction notwithstanding, he dozed fitfully, pistol in hand. Just remember. Carter's one of us. He prayed it was true.

Amy was no better in the morning.

"We should wait," he said.

Even standing seemed to take all the strength she could muster. She made no effort to hide her discomfort, gripping the flat of her belly, her head bowed in pain. He could see the spasms shuddering her abdomen as the cramps moved through her.

"We go," she said, speaking through gritted teeth.

They continued east. The skyscrapers of downtown emerged in their particularity. Some had collapsed, the clay soil having expanded and contracted over the years to pulverize their foundations; others reclined against each other like drunks stumbling home from a bar. Amy and Greer traced a narrow spit of sand between weed-choked bayous. The sun was high and bright. Seaborne wreckage had begun to appear: boats, and parts of boats, splayed on their sides in the shallows as if in a swoon of exhaustion. When they reached the place where the land ended, Greer dismounted, retrieved the binoculars from his saddlebag, and pointed them across the stained waters. Dead ahead, wedged against a skyscraper, lay a vast ship, hard aground. Her stern rose impossibly high in the air, massive propellers visible above the waterline. On it was written the vessel's name, dripping with rust: CHEVRON MARINER.

"That's where we'll find him," said Amy.

There was no dry path across; they would have to find a boat. Luck favored them. After backtracking a quarter mile, they discovered an aluminum rowboat overturned in the weeds. The bottom appeared sound, the rivets tight. Greer dragged it to the lagoon's edge and set it afloat. When it failed to sink, he helped Amy down from her mount.

"What about the horses?" he asked her.

Her face was a mask of barely bottled pain. "We should be back before dark, I think."

He stabilized the craft as Amy boarded, then lowered himself onto the middle bench. A flat board served as a paddle. Seated in the stern, Amy had been reduced to cargo. Her eyes were closed, her hands wrapped her waist, sweat dripping from her brow. She made no sound, though Greer suspected her silence was for his benefit. As the distance narrowed, the ship expanded to mind-boggling dimensions. Its rusted sides loomed hundreds of feet over the lagoon. It was listing to one side; the surrounding water was black with oil. Greer paddled their craft into the lobby of the adjacent building and brought them to rest beside a bank of motionless escalators.

"Lucius, I think I'm going to need your help."

He assisted her from the boat and up the nearest escalator, supporting her by the waist. They found themselves in an atrium with several elevators and walls of smoked glass. ONE ALLEN CENTER a sign read, with a directory of offices beneath. The ascent that lay ahead would be serious; they'd need to climb ten stories at least.

"Can you make it?" Greer asked.

Amy bit her lip and nodded.

They followed the sign for the stairs. Greer lit a torch, gripped her at the waist again, and began to climb. The trapped air of the stairwell was poisonous with mold; every few floors they were forced to step out just to clear their lungs. At the twelfth floor, they stopped.

"I think we're high enough," said Greer.

From the sealed windows of a book-lined office they looked down on the tanker's decking, wedged hard against the building ten feet below. An easy drop. Greer took the desk chair, hoisted it over his head, and flung it through the window.

He turned to look at Amy.

She was studying her hand, holding it before her like a cup. A bright red fluid filled her palm. It was then that Greer noticed the stain on her tunic. More blood was trickling down her legs.

"Amy-"

She met his eye. "You're tired."

It was like being wrapped in an infinite softness. A blanketing, whole-body sleep.

"Oh, damn," he said, already gone, and folded to the floor.

Chapter 47

Peter and the others entered San Antonio on Highway 90. It was early morning; they had passed the first night in a hardbox in the city's outer ring of suburbs, a sprawl of collapsed and scoured houses. The room lay beneath a police station, with a fortified ramp at the rear. Not a DS hardbox, Hollis explained; one of Tifty's. It was larger than the hardboxes Peter had seen, though no less crude-just a stuffy room with bunks and a garage bay where a fat-tired pickup awaited, cans of fuel in the bed. Crates and metal military lockers were stacked along the walls. What's in these? Michael asked, to which Hollis said, one eyebrow raised, I don't know, Michael. What do you think?

They drove out at first light beneath a heavy sky, Hollis at the wheel beside Peter, Michael and Lore riding in the truck's bed. Much of the city had burned in the days of the epidemic; little remained of the central core save for a handful of the taller buildings, which stood with forlorn austerity against the backdrop of bleached hills, their scorched facades telegraphing the blackened and collapsed interiors where an army of dopeys now dozed the day away. "Just dopeys," people always said, though the truth was the truth: a viral was a viral.

Peter was waiting for Hollis to turn off, to take them north or south, but instead he drove them into the heart of town, leaving the highway for narrow surface streets. The way had been cleared, cars and trucks hauled to the sides of the roadway. As the shadows of the buildings engulfed the truck, Hollis slid the cab's rear window open. "You better weapon up," he cautioned Michael and Lore. "You'll want to watch yourself through here."

"All eyes, hombre," came the man's reply.

Peter gazed at the destruction. It was the cities that always turned his thoughts to what the world had once been. The buildings and houses, the cars and streets: all had once teemed with people who had gone about their lives knowing nothing of the future, that one day history would stop.

They moved through without incident. Vegetation began to crowd the roadway as the gaps between the buildings widened.

"How much longer?" he asked Hollis.

"Don't worry. It's not far."

Ten minutes later they were skirting a fence line. Hollis pulled the vehicle to the gate, removed a key from the glove box of the pickup, and stepped out. Peter was struck by a sense of the past: Hollis might have been Peter's brother, Theo, opening the gate to the power station, all those years ago.

"Where are we?" he asked when Hollis returned to the truck.

"Fort Sam Houston."

"A military base?"

"More like an Army hospital," Hollis explained. "At least it used to be. Not a lot of doctoring goes on here anymore."

They drove on. Peter had the sense of driving through a small village. A tall clock tower stood to one side of a quadrangle that might have once been the center of town. Apart from a few ceremonial cannons, he saw nothing that seemed military-no trucks or tanks, no weapon emplacements, no fortifications of any kind. Hollis brought the pickup to a halt before a long, low building with a flat roof. A sign above the door read, AQUATICS CENTER.

"Aquatics," Lore said, after they'd all disembarked. She squinted doubtfully at the sign, a rifle balanced across her chest in a posture of readiness. "Like ... swimming?"

Hollis gestured at the rifle. "You should leave that here. Wouldn't want to make a bad impression." He shifted his attention to Peter. "Last chance. There's no way to undo this."

"Yes, I'm sure."

They entered the foyer. All things considered, the building's interior was in good shape: ceilings tight, windows solid, none of the usual trash.

"Feel that?" Michael said.

A basal throbbing, like a gigantic plucked string, was radiating from the floor. Somewhere in the building a generator was operating.

"I kind of expected there to be guards," Peter said to Hollis.

"Sometimes there are, when Tifty wants to put on a show. But basically we don't need them."

Hollis led them to a pair of doors, which he pushed open to reveal a great, tiled space, the ceiling high above and, at the center of the room, a vast, empty swimming pool. He guided them to a second pair of swinging doors and a flight of descending stairs, illuminated by buzzing fluorescents. Peter thought to ask Hollis where Tifty got the gas for his generator, but then answered the question for himself. Tifty got it where he got everything; he stole it. The stairs led to a room crowded with pipes and metal tanks. They were under the pool now. They made their way through the cramped space to yet another door, though different from the others, fashioned of heavy steel. It bore no markings of any kind, nor was there an obvious way to open it; its smooth surface possessed no visible mechanisms. On the wall beside it was a keypad. Hollis quickly punched in a series of digits, and with a deep click the door unlatched, revealing a dark corridor.

"It's okay," Hollis said, angling his head toward the opening, "the lights go on automatically."

As the big man stepped through, a bank of fluorescents flickered to life, their vibrancy intensified by the hospital-white walls of the corridor. Peter's sense of Tifty was radically evolving. What had he imagined? A filthy encampment, populated by huge, apelike men armed to the teeth? Nothing he had seen even remotely conformed to these expectations. To the contrary: the display so far indicated a level of technical sophistication that seemed well beyond Kerrville's. Nor was he alone in this shifting of opinion; Michael, too, was frankly gawking. Some place, his face seemed to say.

The corridor ended at an elevator. A camera was poised above it. Whoever was on the other side knew they were coming; they'd been observed since they'd entered the hall.

Hollis tilted his face upward to the lens, then pressed a button on the wall adjacent to a tiny speaker. "It's all right," he said. "They're with me."

A crackle of static, then: "Hollis, what the f**k."

"Everyone's unarmed. They're friends of mine. I'll vouch for them."

"What do they want?"

"We need to see Tifty."

A pause, as if the voice on the other end of the intercom was conferring with somebody else; then: "You can't just bring them here like this. Are you out of your mind?"

"I wouldn't ask if it wasn't important. Just open the door, Dunk."

An empty moment followed. Then the doors slid open.

"It's your ass," the voice said.

They entered; the elevator commenced its downward creep. "Okay, I'll bite," Michael ventured. "What is this place?"

"You're in an old USAMRIID station. It's an annex to the main facility in Maryland, activated during the epidemic."

"What's USAMRIID?" asked Lore.

It was Michael who answered. "It stands for 'United States Army Medical Research Institute of Infectious Diseases.' " He frowned at Hollis. "I don't get it. What's Tifty doing here?"

And then the doors of the elevator opened to the sound of weapons being cocked, and each of them was staring down the barrel of a gun.

* * *

"All of you, on your knees."

There were six. The youngest appeared to be no more than twenty, the oldest in his forties. Scruffy beards and greasy hair and teeth clotted with grime: this was more like it. One of them, a giant of a man with a great bald head and ridges of soft fat folded at the base of his neck, had bluish tattoos all over his face and the exposed flesh of his arms. This, apparently, was Dunk.

"I told you," Hollis said, kneeling on the floor like the rest of them, hands on top of his head, "they're friends of mine."

"Quiet." His clothing was a hodgepodge of different uniforms, both military and DS. He holstered his revolver and crouched in front of Peter, sizing him up with his intense gray eyes. Viewed up close, the images on his face and arms became clear. Virals. Viral hands, viral faces, viral teeth. Peter had no doubt that beneath his clothes, the man's body was covered with them.

"Expeditionary," Dunk drawled, nodding gravely. "Tifty's going to like this. What's your name, Lieutenant?"

"Jaxon."

"Peter Jaxon?"

"That's right."

Maintaining his crouch, Dunk swiveled on the heels of his boots toward the others. "How about that, gentlemen. It's not every day we get such distinguished visitors." He focused on Peter again. "We don't get visitors at all, actually. Which is a bit of a problem. This isn't what you'd call a tourist destination."
